Our oral surgeon always talks to us before extracting to find out what is going on. They know the risks of what they are doing and get a medical history before starting. I would not let them extract without insisting they know all that is going on with you. I would prepare a list of everything you want to mention and check it off as you mention it as it is so easy to forget something. Can you ask your medical doctors opinion as well? Also I would ask the nurse when you call about the aspirin. If the tooth is still infected they may not want to extract it yet. Good luck to you.
